Genetic variability, heritability and variance components of some yield and yield related traits in second backcross population (BC2) of cassava
Second backcross population developed from crosses between wild relative Manihot walkarae and Manihot esculenta were evaluated using randomized complete block design at National Root Crops Research Institute (NRCRI) Umudike in 2011 and 2012 cropping seasons. The objective of this study was to assess the extent of genetic variability, heritability, variance components of some yield, yield related traits, pest and...

Effects of light conditions on the growth of commercial seaweed Undaria pinnatifida
The artificial lighting conditions which promoted growth of the gametophytes and sporophytes of brown alga Undaria pinnatifida were examined. The seaweed was subjected to continuous or intermittent white, blue, or red light. There were notable, but not significant, differences in gametophyte and sporophyte growth between continuous and intermittent (104 Hz) white light conditions. Gametophyte growth was promoted most...

Growth, symbiotic and yield response of N-fertilized and Rhizobium inoculated common bean (Phaseolus vulgaris L.)
Common bean (Phaseolus vulgaris L.) is one of the most important and widely cultivated pulse crops in most developing countries. However, its cultivation is globally constrained mainly by low soil fertility and lack of improved agronomic practices. A field experiment was conducted at Hawassa University College of Agriculture, Hawassa Southern Ethiopia to determine the effect of N fertilization and Rhizobium phaseoli...

Curvularia lunata as, a dominant seed-borne pathogen in Dalbergia sissoo Roxb: Its location in seed and its phytopathological effects
Dalbergia sissoo (shisham) seeds naturally infected with Curvularia lunata showed either black discoloration (1.25 to 8.75%) or appeared dull (0.50 to 10.0%). When they were incubated, they yielded pure growth of the pathogen. During location studies, cleared whole mount preparation and component plating revealed the presence of infection restricted to the seed coat and cotyledons of asymptomatic...

New records of basidiomycetous macrofugi from Kurdistan region - Northern Iraq
This study was carried out within February to June, 2015 to 2016 on macrofungi samples collected from different localities within Iraqi Kurdistan region - Northern Iraq. This mountainous region is rich in forest trees with diverse groups of shrubs and herbs and is expected to support the growth of many macrofungal species. However, this part of Iraq is still unexplored from macrofungal point of view. In this paper seven...

Nondestructive maturity assessment tools for commercially viable fruits and vegetables in Uganda
Fruit and vegetable maturity at harvest influences transportation and storage requirements as well as market value. However, small scale farmers in Uganda lack technologies for maturity assessment leading to high pre- and post-harvest losses and low financial returns from fruit and vegetable farms. This study, therefore, assessed the development of fruits (pineapple, passion fruit, watermelon) and vegetables (cabbage,...

Combining ability and heterotic orientation of mid-altitude sub-humid tropical maize inbred lines for grain yield and related traits
Information on the combining ability and heterotic pattern of elite inbred lines is essential to maximize their use in hybrid maize development. This study was conducted to determine combining ability and heterotic pattern of locally developed maize inbred lines for grain yield and related traits. Seventeen inbred lines (10 female inbred lines and 7 tester inbred lines) were used to generate 70 single cross hybrids...

Glycosinolate changes in rapeseed varieties in advanced generations
The aim of this study was to determine the changes in glycosinolate levels that may arise from cross pollination in the advanced generations in rapeseed. With the greenhouse conditions in addition to two different locations, this study was carried out in 3 locations with two varieties and repeated for 3 years. As a result, the changes in glycosinolate levels in the advanced generations were statistically significant....

Oversensitivity of Arabidopsis gad1/2 mutant to NaCl treatment reveals the importance of GABA in salt stress responses
Salt stress is one of the major problems in agricultural fields. Currently, more than 20% of irrigated agricultural lands are affected by salinity. High concentrations of sodium affects plant growth by competing with the uptake of important ions like potassium (K+), and posing osmotic stress. Some plant species developed mechanisms such as modifying cellular metabolism to minimize effects of high salt concentrations....
